A number of you have sent me email suggesting that if you could just see a short, simple working CGI program, it would help so much in getting started.
Emphasis on the word "simple" is what the problem has been. Most "simple" examples seem to have gotten a bit complicated.
Nonetheless, here is a simple CGI program that will display the show times for a specific movie, given a Movie ID (key value). I've also included the HTML for the SHOWTM.HTML file that this CGI program reads and sends to the browser. The folder location name /MOVIES may be different on your machine, or you can create MOVIES and put the HTML in there. This technique does use HTML stored on the IFS.
This CGI program requires the CGILIB, which is part of the RPG xTools. It can also be easily converted to use the popular CGIDEV2 library by changing the /COPY and the CGI procedure names.
FMDB IF E K DISK
F
/COPY XTOOLS/QCPYSRC,CGI
D html S 256A Inz('/movies/showtm.html')
C Callp cgiInit()
C
C Movie KLIST
C KFLD MID
C eval MID = cgiGetVar('MID')
C callp cgiLoadHtmlIFS(html)
C Movie Chain MDB
C if %Found()
C callp cgiSetVar('TITLE':MTITLE)
C callp cgiWrtSection('*TOP')
C Dou %EOF()
C callp cgiSetVar('PLAYTIME': %Char(MTIME))
C callp cgiWrtSection('SHOWTIME')
C Movie READE MDB
C enddo
C callp cgiWrtSection('THERESTOFTHEHTML')
C callp cgiWrtSection('*END')
C eval *INLR = *ON
C
The HTML source is as follows:
The remaining show times for the movie:
/%MOVIETITLE%/ are as follows:
/$SHOWTIME
/$TheRestOfTheHTML
